Connecting PC to Car ISO

Just so I'm totally clear, this connects to the Car ISO thing, right? And it connects to the Audio Out/Headphone port and an AC port?

More specifically, will it let me easily connect this computer to pretty much any car audio input? (Car ISO is a universal standard, right?)

I wasn't getting any replies in the mp3car Store thread, so I'm moving my question here.

I need to connect a CompuLab fit-PC2 to my car's audio. The FitPC will be going into the existing stereo port; is there a way that I can get 12V power from the car's ISO? Is there a 12V / Audio to ISO adapter?

...and are there any guides that you know of that explain fairly well how to replace the OEM unit on a pre-2007 BMW Mini Cooper?

and then wire it to a fused wire that you run from the battery.
(i do not ever recommend splicing into the factory wiring for power-- too many variables, unless you personally designed the electrical system and know that the wire you speced will take the load...)

the headphone to aux is the easy part monoprice.com has some of the cheapest cables-- just get a male-to-male 3.5mm stereo headphone jack at whatever length you need

I'm new to car electronics. When I read this, I imagine attaching wires to the leads on the car battery and stringing those back. Please clarify what you mean by this! I'm easily creeped out by this stuff!
